The daughter of murdered Scot David Haines has told of her anger that the Isis terrorist who abducted her dad has “disappeared” from the US penal system.
Alexanda Kotey - one of four depraved 'Isis Beatles' - is no longer traceable in the custody of the Bureau of Prisons, America’s federal corrections system.
There are fears he may be helping US intelligence services with information on his Isis colleagues in an attempt to get out of jail.
Now Bethany Haines has hit out, demanding Kotey see out his full life sentence in a maximum security facility.
Kotey last year told Bethany, 24, at a face-to-face meeting that it was him who abducted her dad and that he witnessed his torture and murder.
Bethany, from Perth, said: “I was made aware that Kotey had disappeared from the system and it has been impossible to trace where he is.
“That doesn’t seem right because I don’t want to think that he has managed to negotiate his way into any kind of easy treatment on the basis of him assisting authorities or anything else.
“In the past he has been traceable, as we have access to data via the US victim notification scheme, and we at least had the reassurance that he was in a high security facility.
“The last we heard he was in a maximum security jail in Pennsylvania, which is renowned for violence, and I was fine with that because I don’t want to hear about him getting any easy time.
“I don’t think it is right that he can just disappear from the system and the families whose lives were devastated by his actions are left to wonder where he is.”
Bethany was forced to make inquiries with US justice sources to get reassurance that he was still detained somewhere in the country.
The "Isis Beatles" - made up of four Brits - are believed to have abducted and killed 27 people, targeting humanitarian aid workers.
They included British volunteers David and Alan Henning, who were abducted in 2013, and American Kayla Mueller and Peter Kassig.
Kotey pleaded guilty to multiple charges, including conspiracy to commit hostage-taking resulting in death and conspiracy to murder.
Bethany recounted the time she bravely came face to face with Kotey at an arranged meeting in Virginia last June.
The terrorist had agreed to the meeting as part of a deal that would mean he could be transferred to a UK jail after 15 years to serve the rest of his full-life term there.
Bethany said: “When I met Kotey and looked into his eyes I realised there will be no rehabilitating a man like that. He refused to apologise for what he did to my dad.
“He did make an apology in a round about way for the ongoing suffering that my family has to endure but he couldn’t find it within himself to say he was sorry for kidnapping, torturing and beheading my father.”
Bethany said she believes Kotey is still within the US penal system, most likely at a state prison, run outside of the federal system.
She said: “There are various possibilities for him disappearing from the Bureau of Prisons, the most likely being that he is offering assistance to authorities."
Kotey was previously held in the high security federal prison Canaan USP in Pennsylvania but now could be anywhere.
It is understood that the family of former taxi driver Alan Henning, from Salford, has also urged the Biden administration to explain the terrorist’s disappearance and where he now is.
Alan, 47, was also abducted, tortured and beheaded on film by Isis.
A source said: “The families are baffled and understandably want answers."
Bureau of Prisons spokesman Donald Murphy said: “Alexanda Amon Kotey is not currently in the custody of the Bureau of Prisons (BOP). There are several reasons why an inmate may be referenced as ‘not in BOP custody’.
“Inmates who were previously in BOP custody and who have not completed their sentence may be outside BOP custody for a period of time for court hearings, medical treatment or for other reasons.
“We do not provide specific information on the status of inmates who are not in the custody of the BOP for safety, security, or privacy reasons.”
Kotey, from Paddington, London, was sent to Canaan, known as “one of the most dangerous penitentiaries” in America, last August following his conviction in the States.
